Schmitt trigger, and a short-circuit protected open-collector output to
sink up to 25 mA. A south pole of sufficient strength will turn the output
on. A north pole is necessary to turn the output off. An on-board regula-
tor permits operation with supply voltages of 4.2 to 24 volts.
Three package styles provide a magnetically optimized package for
most applications. Package type LH is a modified SOT23W surface-
mount package, LT is a miniature SOT89/TO-243AA transistor package
for surface-mount applications; while UA is a three-lead ultra-mini-SIP
for through-hole mounting. Each package type is also available in a lead
(Pb) free version (suffix,
–T)
, with a 100% matte tin plated leadframe.

variants are being phased out of the product line.
a. Certain variants cited in this footnote are in production but have been determined to be LAST TIME BUY. This classification indicates that sale of this device
is currently restricted to existing customer applications. The device should not be purchased for new design applications because obsolescence in the near
future is probable. Samples are no longer available. Status change: October 31, 2006. Deadline for receipt of LAST TIME BUY ORDERS: April 27, 2007.
These variants include: A3281ELTTR, A3283ELT, A3283ELTTR, and A3283EUA.
b. Certain variants cited in this footnote are in production but have been determined to be NOT FOR NEW DESIGN. This classification indicates that sale of
this device is currently restricted to existing customer applications. The variants should not be purchased for new design applications because obsolescence
in the near future is probable. Samples are no longer available. Status change: May 1, 2006. These variants include: A3280ELHLT, A3280ELT, A3280ELTTR,
